Green tea probably does not help prevent breast, prostate or any other type of cancer, the U.S. Food and Drug Administration said on Thursday.

THE F.D.A. went on to say that studies supporting the assertions about the medical power of green tea are weak.

"Based on these studies, FDA concludes that it is highly unlikely that green tea reduces the risk of breast cancer," released the agency.

"The FDA also concluded that existing evidence does not support qualified health claims for green tea consumption and a reduced risk of any other type of cancer," the agency said.
